    • Capturing clouds: imagin(in)g the materiality of digital networks 

      Pötzsch, Holger (Chapter; Bokkapittel, 2021-01)
      Titles such as the one above – capturing clouds – are ambiguous. Do clouds capture? Or are they themselves captured? Through this double meaning, the title enables a productive questioning of subject-object distinctions and therefore makes possible an interrogation of received notions of agency. In particular, when combining such ambivalences with issues of technology, a redrawing of arrows ...

      Bergan, Veronica; Krempig, Inger Wallem; Utsi, Tove Aagnes; Bøe, Kari Wallem (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-14)
      Learning and development in early childhood is highly dependent on social interaction and exploration through continuous encounters with the real world. Foraging and gardening are outdoor pedagogical practices that have relevance to education for sustainability. Previous work suggests that engagement in such activities can be characterized by the concept “community of practice” (CoP). In this paper, ...
    • Pan-Arctic suitable habitat model for Greenland halibut 

      Vihtakari, Mikko; Hordoir, Robinson; Treble, Margret A; Bryan, Meaghan D.; Elvarsson, Bjarki; Nogueira, Adriana; Hallfredsson, Elvar H.; Christiansen, Jørgen Schou; Albert, Ole Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-08)
      Deep-sea marine fishes support important fisheries but estimates of their distributions are often incomplete as the data behind them may reflect fishing practices, access rights, or political boundaries, rather than actual geographic distributions. We use a simple suitable habitat model based on bottom depth, temperature, and salinity to estimate the potential distribution of Greenland halibut ...
